Having just been promoted, Aoi's husband eagerly invited all his siblings to throw a celebratory party, among whom was the only brother, who was also the charming womanizer of the family with his dashing appearance and generosity. Ironically, it was precisely this womanizing nature that caused countless girls to lose their composure, yearning to be close to Aoi's brother, including Aoi herself, the lustful wife. Throughout the party, she kept her attention on him, clinging to his side until her husband fell asleep at the dinner table from drinking too much, and as everyone began to prepare to leave, this became the real opportunity for the two of them. The days that followed were also the time these two had wonderful secret moments together, and they even took the initiative to use a camera to capture these memorable moments.
